14/2.99=1/x
14x=2.99(1)
x=2.99/14
x=0.213571429
We know that
Applying the Pythagoras Theorem
c=²=a²+b²
where c is the diagonal of the wall
a=12 ft
b=6 ft
c²=12²+6²-----> c²=144+36-----< c²=180-----> c=√180------> c=6√5 ft
the answer is
<span>the exact length of the brace is 6</span>√5 ft
Answer:
13, 13√3, 26
Step-by-step explanation:
30 60 90 right triangle
Ratio of short leg : long leg : hypo = a : a√3 : 2a
Given short leg = 13, so long leg = 13√3 and hypo = 13 * 2 = 26
Answer:
13, 13√3, 26
Answer:
∠KNC and ∠KMC are right angles
∠MCN = 25°
Step-by-step explanation:
if KM and KN are tangent lines, then they are perpendicular to the radius going through the tangent point, so therefore right angles are:
1. ∠KNC
2. ∠KMC
the outside angle of a circle is equivalent to half the measure of the intercepted arc, so
if ∠MKN = 50°, then ∠MCN = 25°
